Introduction to cryptography: theoretical and appropriation foundations of information protection. Disa E.I., Kotova L.V.

The textbook is intended for studying the courses “Methods and means of information protection”, “Fundamentals of cryptography”, other related disciplines of basic educational programs of higher education, for studying the disciplines on choices devoted to the basics of cryptography and applied issues of the theory of numbers.

The manual includes theoretical facts, exercises and tasks of various difficulty levels in all basic sections of cryptography and the corresponding sections of the applied numbers theory. In addition to the extensive list of exercises and tasks, the manual presents individual tasks for creative and laboratory work, control issues and standard tasks of the mandatory minimum for each topic. The manual was compiled in accordance with the requirements of federal state educational standards of higher education and approximate basic educational programs of higher education.

The book is written on the basis of many years of experience in practical work of the authors, its material was built on the modular principle: the choice of the studied sections, the procedure for dating With them, the depth of the development of relevant theoretical and practical issues depends on the direction of training and the profile within which training is carried out. The manual is intended for teachers and students of higher educational institutions, primarily mathematical faculties of pedagogical unions, teachers of a profile school, high school students interested in applied theoretical and distribution problems, all who are attracted to history and modern trends in cryptography. It is useful to be useful for organizing individual educational and research work of students in the framework of the preparation of coursework, graduation qualification works of bachelors and master's thesis.
